Not interested in Smiths
Hello
nanoVNA without technicality seems unnatural to me. It is a measuring device; you must therefore master what it measures, otherwise it will not be too useful to you.
The current use of the Smith has nothing to do with the use for which it was designed and used. Before, we used the Smith, at a fixed frequency, to calculate graphically. Now we use the Smith to represent, in a frequency band, an impedance. With computers, there is no point in making calculations graphically: it is long and imprecise.
You will notice that the Smith that appears on the nanoVNA is not scaled and the graph you see is a trace because the frequency is swept.
